Answer:
True.
Step-by-step explanation:
Given,
4cos2 (4x) - 3 = 0
Now, 4π/24 = π/6
Or, cos π/6 = √3/2
Or, cos^2 π/6 = 3/4
Or, 4 cos^2 π/6 = 3
Now, Left Hand Side= 4cos2 (4x) - 3
= 3-3 =0 = Right Hand Side (Proved)
Here, Left Hand Side= Right Hanad Side. So, 4cos2 (4x) - 3=0 is true.
The letter or symbol expresses an unknown value. There is no value to a letter or symbol.
I think is C. 1 client and 24 hours
because
12÷3=4
4÷4=1
6×4=24
ratio
client: hours
1 : 4
.18 * 27.32 = 4.9176
18% of 27.32 = 4.91
4.91 + 27.32 = 32.23
If Michael and Imani add an 18% tip to 27.32, their lunch cost will be $32.23 in total.
Hope this helps you! (:
